Question

Quizplus · Accepted Answer

Control groups serve as the guard against the effects of the experiments themselves as well as events outside the laboratory because they are not exposed to the treatment being tested and provide a baseline for comparison. Variable groups are those that receive the treatment being tested and are compared to the control group, posttest groups are the groups that are tested after the treatment has been administered, and administrative groups are not typically used in experimental designs.
